For one, case tracker is different than project/issues (there is no "suggestion" on drupal.org either, nor is there a text modification).

The other is that for this site in particular, splitting between a development task (i.e. someone that can code needs to go off and do this) vs. soft tasks like documentation etc. is useful. When people show up and ask, "How can I help?", there is an entire set of issues that need development.

And what the hell is "Text modification"? Changing that to "documentation" would probably make more sense...
